SPECIFICATION forming To all whom/it may concern:

Be it 'known that we, M. Wrsnnnr f, attached to :a plate, f, bolted on the axle.

and NVILLIAMF. Bnzrok, both of Topeka, in

the county of Shawnee and State of Kansas,

have invented a new and Improved Roller Attachment to Grain-Drills, of which the follow ing is a full, clear, and exact description. i

Our invention consists of improved arrangements of roller attachments to grain-drills, and means for connecting the same to the drill, the object of which is to provide a roller attachment oflbetter action, and being more substantial and durable than any now in use, all as hereinafter fully described.

Reference is to be had' to the accompanying drawings, forming part of this specification, in which similar letters of referenceindicate corresponding parts in all the figures.

Figure 1 is a front elevation of the roller attachment and transverse section of the rods that connect it with the drill-axle, the section being taken on the line was of Fig. Fig. 2 is a side elevation of the roller attachment and a section of the grain-drill, said section being taken across the axle. Fig. 3 is a side view of the connecting device employed to connect the roller-axles and the connecting-rods on an enlarged scale. Fig. 4c is a side elevation of a joint of the roller-frame, also on an enlarged scale. Fig. 5 is a side elevation of one of the joints connecting the roller-frame with the roller-axles, also on an enlarged scale. Fig. 6 is an elevation of the joint of Fig. 4 in aplane at right angles to the plane of said figure. Fig. 7 is an elevation of joint, Fig. 5, at a right angle to the plane of that figure. Fig. 8 is'a side elevation of the attaching-bar bywhich the connecting-rods of the rollerattachment are coupled to the axle of the grain-drill. Fig. 9 is a plan view of a section of the axle of the grain-drill and part of the roller attachment. Fig. 10 is a detail of Fig. 9 on an enlarged scale, and Fig. 11 is a plan view of the adjustable and vibrating coupling of the connecting-rods.

We arrange a series of pairs of rollers, a, on a short axle, b, to each pair in a line, and connect them to the axle c of the grain-drill by a branched connecting-rod, d, to each pair, the branches e of said rods connecting with the projecting outer ends of the axle, and the upper part of Letters Patent No. 293,389, dated February 12 1884.

ends of the said rods having aThead, 6, connecting with the axle by a couple'of eyebolts,

throughthesocket has a series of holes for taking up. or letting out the lengthofthe connecting-rod. The sideskofthesocket are extended along the bar to a greater length than the top of the socket, to form stops to preventtoomuch lateral play of the rollers. It will be seen that this joint enables the connecting-rods to be lengthened and shortened at will to connect with high or low drills, and allows all the neces sary vibration for free and easy action; also, that it is a substantial and durable, as well as simple, joint. The connection with the axle c is also simple and substantial; likewise, the connection with the roller-axles is of' a durable and also simple character, the latter connection consisting of a cast-metal box, Z, which slips onto the end of the axle, and is then fastened to the end of a branch, 6, of the connecting-rod, which is made to fit in the recess m, and is bolted therein.

The wheels are thus secured on the axle without other fastenings; also the connecting-rods. Between the wheels each axle b has a sleeve, at, extending from one wheel to the other, to form shoulders for the insides of the wheels, and also to support the seat 0 of a rule-joint p, of a roller-frame, consisting of the uprights g, each of which rests on the axle of a pair of wheels. The top of this" rolierframe forms the seat of another rulejoint, 1), whereon one leg of a seat-frame, s,

rests, the other leg similarly resting on the up happen to drop into a low place. It will be seen that by these joints the weight of the practice, also have an extensible joint to shift as the connecting-rods are shifted.

\Ve do not abandon or dedicate to the public any patentable feature set forth herein and not hereinafter claimed, but reserve the right to claim the same, either in a reissue of any patent that may be granted upon this application, orin other applications for Letters Pat ent that We may make.

Having thus described our invention, what We claim as new, and desire to secure by Letters Patent, is

1. 111 a graiirdrill, the combination, with each pair of rolls, of a rod, (Z. connecting with the axle, and having two branches, 0 c, fitted at the ends with separable bearings which receive the outer ends of the roll-axle, as shown and described.

The seat-brace a will, in

2. The frame-sections and roller-axles, connected by knuckle-joints, sustaining the load and the wear independently of the joint-pin, and having shoulders a, that limit the lateral vibration, substantially as described.

3. The combination, with the seat frame, of the axles b, sleeves n, and rule-joints p, having seats 0, whereby said frame may be sup' ported, as described. A

4. The independent pairs of rollers a, con-- nected to the drill-axle by an extensible and vibrating connecting-rod, (Z, made in two parts, one having a socket and the other being inserted in said socket and fastened with a pin, substantially as described.

5. A roller attachment for grain-drills, consisting of indepenchznt pairs of rollers connected to the axle of the grain-drill by independent connnecting-rods, said rods having an extensible and vibrating joint, and being connected to the axle by a T-head and eyebolts, substantially as described. 7 JAMES M.
